Title:
SCRAPER CONVEYOR CHAIN BREAKAGE REAL-TIME MONITORING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/085674
Kind Code:
A1
Abstract:
A scraper conveyor chain breakage real-time monitoring system comprises a plurality of scrapers (5), convergence nodes (3), data transmission nodes (8), and tension strain gauges (9). The tension strain gauge (9) is flat-fit to a flat chain ring (7) in an annular slot of a scraper chain. The scraper (5) has a cavity (12) at both ends. The data transmission nodes (8) are packaged in the cavities (12). The tension strain gauge (9) is connected to the data transmission node (8). The convergence nodes (3) are disposed on two sides of a machine head sprocket (2) or a machine tail sprocket (11). The monitoring method uses change of tension on two chains and the offset relationship between node positions at two ends of the same scraper as a chain breakage indicator, so as to accurately detect chain breakage on a scraper conveyor, enabling timely shutdown, adjustment, and replacement, and preventing serious accidents, damage to devices, and injuries on a production line.
